The central chemoreceptor responds to hydrogen ions generated from the dissociation of hydrogen from carbonic acid and lactic acid produced by active skeletal muscle.

Question

Quizplus · Accepted Answer

The central chemoreceptor primarily responds to changes in the partial pressure of carbon dioxide (PCO2) through the detection of hydrogen ions (H+) generated from the dissociation of carbonic acid (H2CO3), not directly to lactic acid produced by active skeletal muscle.
